The Animal and Plant Health Agency (APHA) are reminding woodland managers, tree professionals and the plant trade to be vigilant over the coming months for sweet chestnut blight, caused by the fungus Cryphonectria parasitica.  Suspected cases in trees and woodland should be reported to the Commission with Tree Alert. Suspected cases in chestnut plants moving in trade, such as in garden centres and nurseries, must be reported to APHA’s Plant Health & Seeds Inspectorate (PHSI) on 01904 405138 or planthealth.info@apha.gsi.gov.uk.
